A square pyramid has a base with an area of 20 square meters, and its lateral faces have a slant height of x meters. Sydney is constructing a second square pyramid with the same size base, but the lateral faces of her pyramid have a slant height twice as long, 2x. Which statement best describes how the surface area of Sydney’s pyramid compares to the surface area of the original pyramid?

A: Sydney’s pyramid will have the same surface area because the One-half in the expression for the area of the triangular faces will make up for the slant height being doubled.

B: Sydney’s pyramid will have the same surface area because the slant height is not used when finding surface area.

C: Sydney’s pyramid will have a surface area that is exactly double the original pyramid’s because the slant height is used when finding the area of every lateral face.

D: Sydney’s pyramid will have a surface area that is greater than the original pyramid’s but not double the area because the slant height is not used when finding the area of the base.

(PS: If you choose C, you're wrong.)

What option are you talking about for, is it for your quiz or for your classwork

Answer:

  p = 2

Step-by-step explanation:

A rational function has a vertical asymptote where the denominator is zero.

__

Your function will have a denominator that is zero when ...

  x -p = 0   ⇒   x = p

We are told there is a vertical asymptote at x = 2. That means ...

  p = 2

Answer:

[tex]4*\frac{1}{6}[/tex]

Step-by-step explanation:

The number lines end points are 0 and 1 so the whole number line has a value of 1.

The number line is also broken up into 6 sections.

Then we have the pink rectangles that cover up each section. There are 4 of them and each cover 1/6 of the number line

So the expression that would represent the model would be 4 x 1/6

Answer:

4 * 1/6

Step-by-step explanation:

So to begin, I would find out what all the answers are equal to.

4 * 1/8 = 4/8 = 1/2

4 * 1/4 = 4/4 = 1

4 * 1/6 = 4/6 = 2/3

4 * 1/3 = 4/3

Next I would rule out all the answers bigger or equal to one, so 4 * 1/4 and 4 * 1/3.

Last, this fraction splits one into six parts, and 4 parts are highlighted. 4/6 is equal to 4/6. Your answer is 4 * 1/6

Answer:   x^2+4

Work Shown:

x = -2i

x^2 = (-2i)^2

x^2 = 4i^2

x^2 = 4(-1)

x^2 = -4

x^2+4 = 0

Side note: Since -2i is one root, this means 2i is the other conjugate root.

[tex]\text{For quadratic equations, if one root is complex, the other root will be its conjugate.}\\\\\text{So, the roots of the second degree polynomial are}~ \alpha = -2i ~~ \text{and}~~ \beta =2i \\\\\text{The equation is,}\\\\~~~~~~~x^2-(\alpha + \beta) x +\alpha \beta = 0\\ \\\implies x^2 -(-2i+2i)x +(2i)(-2i)=0\\\\\implies x^2 -0\cdot x -4i^2 =0\\ \\\implies x^2 -4(-1)=0\\\\\implies x^2 +4=0[/tex]

Answer:

48

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180°.

We know one angle measures 42°.

Another angle is a right angle, so it measures 90°.

Only the angle labeled x is unknown.

42 + 90 + x = 180

132 + x = 180

x = 48

Answer: 48

The sum of the first 10 terms of the given geometric series 300 +360+432 +518.4+..... is 7787.60.

Let's suppose its initial term is  a , the multiplication factor is  r

and let it has total n terms, then, its sum is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

For the given geometric series, the common ratio is,

r = (360/300) = 1.2

Also, the first term of the series is 300. Therefore, the sum of the first ten terms of the series are:

Sum = a(rⁿ-1)/(r-1) = 300(1.2¹⁰-1)/(1.2-1) = 300(5.1917)/0.2 = 7787.60

Hence, the sum of the first 10 terms of the given geometric series is 7787.60.

Answer:

Graph B

Step-by-step explanation:

Replace y with x and vice versa.

y=1/2x+2 becomes x=1/2y+2

Then solve for y. Subtract 2 from both sides, then multiply by 2 which results in:

y=2x-4

Graph B is the one that has a y-intercept at -4 and a rise/run of 2.

Answer:

17, 18, 19, 20

Explanation:

Let the numbers be x, x + 1, x + 2, x + 3

Their sum is equals to 74

x + x + 1 + x + 2 + x + 3 = 74     (group the variables)

x + x + x + x + 1 + 2 + 3 = 74    (simplify)

4(x) + 6 = 74                             (subtract both sides by 6)

4x = 68                                     (divide both sides by 4)

x = 17

Other numbers:

x + 1 = 17 + 1 = 18

x + 2 = 17 + 2 = 19

x + 3 = 17 + 3 = 20

Answer:

17, 18, 19, 20

Step-by-step explanation:

Answer: F(x) = 4x - 16

Step-by-step explanation: G(x) = 4x

if F(x) is the graph G(x) shifted over to the right by 4 then

F(x) = G(x-4) = 4(x-4) = 4x - 16

The general equation is f(x - amount_shifted)

The equation of the graph of the function F(x) is F(x) = (x - 3)⁴.

Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.

There are horizontal translation and vertical translation of functions.

Given a function F(x) and G(x).

Given that,

F(x) has the same shape as the graph of G(x) = x⁴.

The difference is that F(x) is shifted to the right 3 units.

A function G(x) when shifted right to k units becomes G(x - k).

So the function F(x) is,

F(x) = G(x - 3)

      = (x - 3)⁴

Hence the correct option is B.

[tex]\frac{2\pi }{3} \ ,\ \pi \ ,\ \frac{4\pi }{3}[/tex]

Step-by-step explanation:

suppose cos(x) = y

Then

[tex]2\cos^{2} \left( x\right) +3\cos x+1=0\Longleftrightarrow \begin{cases}2y^{2}+3y+1=0&\\ y=\cos \left( x\right) \ \ \text{and} &0\leqslant x\leqslant 2\pi \end{cases}[/tex]

2y² + 3y + 1 = 0 ⇒ y = -1 or y = -1/2  (because 2-3+1=0)

y = -1 ⇔ cosx = -1 ⇒ x = π  (because x∈[0,2π] )

y = -1/2 ⇔ cosx = -1/2 ⇒ x = 2π/3 or x = 4π/3

Final answer :

x = π or x = 2π/3 or x = 4π/3

The amount of pizza left over in the fraction form will be 1/4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the swim team is sharing 6 pizzas. There are 36 players on the team. If each member has 1 slice, and each pizza has 8 slices.

Total slices = 8 x 6 = 48
